Description
The TPS40305EVM-488 is designed to use a regulated 12-V (8V – 14V) bus voltage to provide a
regulated 1.8-V output at up to 10A of load current. The TPS40305EVM-488 is designed to demonstrate
the TPS40305 controller and TI NexFETs in a typical 12-V bus to low-voltage application while providing a
number of non-invasive test points to evaluate the performance of the TPS40305 and TI NexFETs in a
given application.
